As a re-
sult, it was necessary to employ decontamination measures with the
marine craft which had been anchored near Enyu during SH7S “in
order to permit evacuation of these craft to Eniwetok Atoll.
Also
close control of personnel exposure records and assignment to contaminated work areas was necessary in order that no individual

On 12 May an LCU was dispatched to Rongerik Atoll via the USS
BELLE GROVE to dismantle and remove the equipment from the JTF
SEVEN weather station which had been evacuated after SHo7/.
With
the return of this equipment to Eniwetok, all material involved in
the post+SH07S roll-up had been removed to Parry Island.
The
post+SHo7G scientific data and equipment recovery program was started 17 May at Eniwetok and progressed smoothly to completion on 20
May.
Other equipment on Parry Island which had been brought from
Bikini. or Rongerik or which had been declared surplus for interim
period needs was either removed or placed in mothballs.
The unused
test materials, regardless of classification or accountability,
were returned to the ZI aboard the CURTISS and, upon arrival on
the west coast, were transported to final destinations under the
direction of AEC.
A major item of deactivation for the Scientific Task Group was
the mothballing of the TU 2 cryogenics plant and associated equipment.
